Happy to see our overclocking work gaining traction:

Overclocking the Cloud? Immersion Cooling Could Enable Faster Servers (datacenterfrontier.com)

Our latest research in liquid cooling addresses the concept of overclocking, which is to opportunistically operate components beyond their pre-defined voltage, thermal and power design limits to further improve performance. Based on our tests, we’ve found that for some chipsets the performance can increase by 20% through the use of liquid cooling [1]. This demonstrates how liquid cooling can be used not only to support our sustainability goals to reduce and eventually eliminate water used for cooling in datacenters, but also generate more performant chips operating at warmer coolant temperatures [2]

You can refer to articles here for more details on our research:

Very cool stuff, Marcus and team! I'd love more detail on the goal of 95% reduction of water use in evaporative cooling. The blog post states "Through our extensive global research on server performance in warmer temperatures, we’re able to create higher set points for a variety of different climates for when water-based, evaporative cooling is necessary to preserve server performance and reliability. We expect this project to be fully implemented by 2024, and it has the potential to eliminate water use for cooling in regions like Amsterdam, Dublin, Virginia and Chicago, while reducing water use in desert regions like Arizona by as much as 60%." That's really awesome, but I'm super curious to learn more details on what enables this level of reduction, clearly the 'higher setpoints' alone would be nowhere near sufficient. I'm guessing the evaporative cooling (presumably through water source heat pumps) is being replaced with something else, whether high-flow ambient air exchange, or some other heat transfer mechanism other than evaporative cooling.

I was wondering when this would come into the fray!
